The focus of the paper is on the coordinate model and calibration of multi-joint type CMM. Begining with a generalized model of a pair unit
by which the coordinate model of a Multi-Joint Type 3D Scanner (MJT3DS) system can be easily deduced. The paper presents a new approach to the calibration of parameters in the model. Based on the real-valued genetic algorithm
the calibration algorithm is superior in many respects to the linear algorithm applying least square and iterative algorithm. The feasibility and robustness of this algorithm have been proved by computer simulation.
